Letters Patent No. 95,990, dated October 19, 1869.

IMPROVE!) METALLIC ROOFING.

The Schedule referred to in these'L-etters Patent and making` part ofthe lame.

To all whom it may conce/rn.-

Be itknown that I, JOB B. Gnou/Lm', of Middletown, in the county ofMidqiesex, and State of .Gonnecticut, have invented a new Improvement inEnamelled Corrugated Roong and I do hereby declare the following, whentaken iu Connection with the accompanying drawings, to be a full, clear,and exact description of the same, and which said drawings constitutepart of this specification, and represent, 1n-

Figure l, a top view of a piece of roong, and in Figure 2, a transversesection of the same.

This invention'relates to an improvement in metal roofing, and isespecially adapted -to that commonly known as corrugated roofing, theobject being to avoid the use of pain t ating, which wears awaysoastorY" d The invent-ion consists in coating themetal, uponone or both sides,with loorc'elaicl'ay,` 6r other vitreous material, while in aplastmstate, then', by heat `or otherwise, hardening the coating..

To enable others skilled in the art to make and my invent-ion, I willfully describe the same, illustrated in the accompanying drawings.

By preference I form the metal in plates,`as seen in iig. l, the severalplates corresponding in size, and corrugated as seen in section, iig. 2,eachy plate being perforated, as a means of securing to the roof'. l

'Then I coat upon the upper side, (and, by prefer ence, both sides,)byspreading thereon a coating of porcelain-clay, or other vitreoussubstance, while in-a plastic state, and then harden the Coating bysubjecting it to the heat or a drying-process, aud when hardened, theroofing is ready for use, to be applied in the usual man ner of similarmetal roofing.

This coating is not affected by the atmosphere, and. is notV in theslightest degree worn away, as other coating, or paint. i Having fullydescribed my invention,

What I claim as new and useful, and desire to secure by Letters Patent,is

As a new article of manufacture, metallic roofing,4

coatedv u'pon one or both sides, with porcelain, or

other vitreous material, snbstantiallyas set forth.
